SUBSTITUTE FOR 'CELLULOID.

No Drawing.

To all whom it may concern:

Be it known that I, HERMANN HnYni-lx- UAUSS, a subject of the Emperor of Austria- Hungary, residing at I Tuehlauben 8, Vlenna, Austria-Hungary, have invented certain new and useful Improvements in' Substitutes for Celluloid, of which the fol- E moss, an acid. and alcohol.

lowing is a specification.

The present invention relates to the manufacture of a substitute for celluloid, and

has for its object to provide such a substitute which possesses the transparency and the tenacity of celluloid and can be workedand polished equally as well, but which has the in'iportant advantages over celluloid that t it is not inflammable, is inodorous, tasteless and does not, in any way affect the health of the manufacturer or user.

-According to my invention, a mixture of glue, gelatin, or of other animal albumin, and a solution of carrageen moss is treated with acetic acid, or other acid, and alcohol,

' and the mixture is hardened with'formalde hyde or similar hardening agen't. The resulting product shows a Superior degree of flexibility and capability of better working, when compared with another known celluloid substitute consisting of glue hardened with formaldehyde, or when compared with a product obtained by treating a mixture of glue agar-agar with formaldehyde.

The following is an example of the manner of manufacturing the new product: 25 parts glue or gelatin are mixed in the swelled condition with 10 parts of a saturated solution of carrageen moss, and then ten parts vinegar or dilute acetic acid and 10 parts alcohol are added. The addition of the alcohol prevents the formation of bubbles. .The mixture is made with the Specification of Letters Patent. Application filed September 2, 1909. Serial No. 515,922.
